Abstract
A focal-plane shutter is provided with a driving member that drives a fore-blade, a setting component that sets the driving member into a set position prior to a shutter action, a component being attracted provided in the driving member, and electromagnets that exert attracting action by means of electrical conduction to the component being attracted under a condition where the driving member is set into the set position. The component being attracted includes an axis, a part being attracted on one end of the axis, and a flange having a curved surface curved in a convex manner on the other end of the axis. The driving member includes through-holes at designated intervals that go through the axis and two flat inclined surfaces that receive the curved surface of the flange in two locations.
